GEORGE STIEFEL, OF CHICAGO, ILLINOIS.

BUNG-CLOSURE.

T0 all whom it may concern:

Be it known that I, GEORGE STIEFEL, a subject of the Emperor of Germany,and a resident of Chicago, Cook county, Illinois, have invented certainnew and useful Improvements in Bring-Closures, of which the following isa specification.

The essential objectof this invention is to provide a bung-closurewhich, in certain respects, is an improvement upon and addition to thebung-closure which is shown and described in my pending application 'forpatent filed August 8, 1911, Serial No. 643,002. The closure shown anddescribed in the aforesaid application is particularly adapted for usein connection with the head of a barrel, whereas the bung-closure shownand described in this application is one which is primarily designed tobe applied to a bung-hole which is bored through one of the staves ofthe barrel at or near the bilge.

In the drawings, Figure 1 is a top plan view looking toward the barrel,part o'E the outer casing being broken away; Fig. 2 is a View similar toFig. 1, the movable parts being shown in dotted lines and in a differentposition from that depicted in Fig. 1; Fig. 3 is a sectional view takenon the line 3-3, Fig. 1; Figs. 4 and 5 are sectional views of thebotttom cap, Figs. 4 and 5 being in inverted position as compared toFig.`3; and Fig. 6 is a View of the bung-closure with the device :foroperating the valve applied thereto, some of the parts being shown insection and some in elevation.

The casing 1 is cylindrical in shape and is provided with external screwthreads 2 adapted to be screwed into the bung-hole of the barrel. Thebottom cap 3, the construction of which will hereafter be morespeciically described, may either be screwed upon the bottom of thecasing or may simply be driven into position, this last-namedconstruction being the one shown in the drawings. The circular closureplate or valve 7 provided with the aperture S is placed above the bottomcap 3. The plate bears a pin 17 which is received within the slot 16upon the arm 13. To this arm 13 is connected the boss 14, within whichthere is formed the hexagonal aperture 15. It will be noted that up tothis point the invention has been described using the same referencenumerals as those employed to denote like parts in the aforesaidapplication, Serial Specification of Letters Patent.

serial no. 773,133.

No. 643,002, wherein the construction and operation oi' said parts aremore specifi tally described.

Projecting outwardly 'from the casing l, and ijn'eierably il'ormedintegral therewith, are large ears or plates 18. Since the device in itscompleted form is usually several inches in diameter, the particularstave which is provided with the bung-hole might be unnecessarilyweakened by the boring ot' a large bung-hole. In the drawings, afragment oil the stave 19 which is bored is shown in. Fig. 1 ol. thedrawings, and the ears or projecting plates 18 protrude outwardly fromthe bung-closure beyond the edge ot' that stave. Said members 18,therefore, will rest upon and engage those staves which are respectivelyon one side or the other oi' the stave 19 and in this manner will serveto reinforce said stave and prevent the same 'trom caving in or breakingin case the weight of the barrel should happen at any time to rest uponthe bored stave 19.

The casing 1 is provided with the perforation 2O which extendsvertically therethrough, and within said perforation 20 the boss 14 isreceived, there being preterably a shouldered seat 21 in the perforation20 to receive the boss 14. The circular closure plate 8 is directlybeneath and in engagement with the boss 14 and arm 13, and said plate iscaused to revolve when the arm 13 is rotated. Said arm is adapted to becarried -lrom the position shown in Fig. 1 to that depicted in Fig. 2.Then the parts are in the position shown in Figs. 1 and 3, theperforation 8 in the rotatable plate 7 will register with the opening20, but when the parts are in the position of Fig. 2, the rotatableplate will close the opening 20.

The bottom plate 3, as shown in Figs. 4 and 5, is provided `with a boss22 which is preferably screw-threaded on its interior wall, and the ring23, which is provided with screw-threads upon its outer wall, is adaptedto be received within said boss 22. Said ring 23 bears an annular seat24, and upon this seat rests a ring or web of packing or the like. Thescrew threads upon the inner wall of the boss 22 do not extend to thetop of the boss in Fig. 3 or to the bottom of the boss in Figs. 4 and 5,but at the bottom, Fig. 4, the inner wall of the boss 22 is smooth andthe packing 25, therefore, is received between a smooth surface upon thewall of boss 22, and between a smooth surface on the outer edge of thering 28. As clearly shown in Figs. 4 and 5, the web of packing projectsa short distance beyond the ring 23 and the plate or cap 3, and isadapted to press against the closure plate 7 and in this manner to forma tight joint., 1When the parts are assembled, the central aperturethrough the ring 23 and the boss 22 is in registration with the aperture20. When the movable parts are as depicted in Figs. l and 3, theaperture 8 will likewise be in registration with the aperture 2O andwith the aperture through the ring 23; but when in the position shown in2, the plate T will close the passageway through the device. Any liquoror liquid which may be within the barrel may press upon the undersurface of the plate 7, but none of the liquid can escape because of thetight joint resulting from the engagement of the packing 25 upon therotatable pl ate 7.'

A wrench with an ordinary hexagonal head may be used to open and closethe valve, but since it is desirable to have such wrench used inconjunction with some kind of a lling head, a device like that shown inFig. G may be employed. ln said gure there is shown a handle 26 which isattached to the casing 2i". The casing is of just the proper diameter tobe received within the aperture 20, and at its lower end bears thehexagonal head 2S. llhe pipe 29 is secured in any suitable manner withinthe casing i7, some kind of a joint being used by which the pipe neednot turn even though the handle and the casing are turned. lf so desiredpipe may extend downwardly from the hexagonal h ead 28 to reach thebottom of the barrel, but such a pipe, which is not shown in thedrawings, would have to be removed before the valve could be closed.

The ring 28 is preferably provided with slots or notches 8O to afford agrip` for whatever tool may be used to screw or unscrew the ring 23.

It is obvious that many changes in the details of construction andarrangement of parts may be made without departingg from the scope ofthe invention or of the various claims.

l claim as my invention:

l. A bung-closure comprising a casing, a bottom member receivedtherewithin, a boss upon said bottom member, said casing and said bossbeing provided with registering apertures, a ring adapted to be securedwithin said boss, a packing adapted to be retained between the ring andthe boss, a rotatable valve disposed between the top of said casing andsaid'boss, said valve being normally in engagement with said packing,and means to rotate the Valve.

it. A bung-closure comprising' a casing, a bottom member receivedtherewithin, a boss upon said bottom member, said casing and said bossbeing provided with registering apertures, a ring` adapted to be securedwithin said boss,a packing adapted to be retained between the ring andthe boss, those surfaces of the boss and of the ring whichengage saidpacking being smooth at the point of engagement, a rotatable valvedisposed between the top of said casing and said boss, said valve beingnormally in engagement with said packing, and means to rotate the Valve.

j A bung-closure` comprising a casing having an aperture therethrough, ashouldered seat within said aperture, a bottom member received withinthe casing and having a packing member in connection therewith, arotatable valve engaging said packing member and located between saidbottom vmember and said seat, an arm, a boss thereupon, said boss beingreceived within said seat, and means to rotate the arm, thereby torotate the valve.

ln testimony whereof l have hereunto affixed my name in the presence oftwo witnesses.
